[The distribution of ABO system blood groups in patients with unilocular echinococcosis].

The distribution of the AB0 blood groups was investigated in 624 patients with echinococcosis operated on and in 579 persons whose sera were subjected to IHAT with echinococcosis diagnosticum. Higher disease incidence was recorded in patients with the A (II) blood, especially in males, as compared to the controls. Simultaneous involvement of the liver, lungs and other organs was more common in them. Rh-positive patients predominated both in the A (II) and control groups. Blood group distribution with regard to IHAT findings failed to reveal any regular features.
